There is a lot of choice in the world of business messaging, and supporting all the different messaging channels consumers want to use can be challenging for businesses. With an omnichannel messaging API, you can make it easy to add new channels without extra development work. Twilio is bringing support for Rich Communications Services (RCS) to its Programmable Messaging and Verify APIs, enabling businesses to send messages over WiFi and cellular connections with higher security, utilize branded profiles, and include rich messaging features like cards and carousels. With this update, Twilio will automatically upgrade SMS messages to RCS when available, ensuring the highest deliverability for recipients and personalizing channels based on messaging data.
